For example if canaanites are Hamites,why are they(Coastal lebanese ) indistinguishable from modern day jews genetically??where did the natie americans and asians come from?What about australian aboriginals,are they hamites?How do we explain denisovan dna and difering rates of neanderthal dna in different ethnic groups if the flood wiped out neanderthals and neanderthals were simply pre-flood men or some say a post flood tribe?

I'm interested in any creationist/christian/Jewish/muslim answers to this?It seems the linage of shemites is very accurate but it also leaves out a whole lot of europe,native america and eastasia and polynesia.
